The outer green glaze on these cone 6 porcelain mugs has a high melt fluidity. The liner on the upper mug is G3806C, a fluid melt high gloss clear. The liner glaze on the lower one, G2926B, is high gloss but not highly melt fluid. Thus, when both the outer and inner glazes have high melt fluidity (upper mug), they bleed together forming a fuzzy boundary. But when even one of them is not, a crisp boundary is achieved (lower mug).
